SLI will also give you stutter :P You need a more powerful single-GPU card instead... Like a Titan or something :wink:

Really? I need to look into this a bit more.

Nvidia's Scalable Link Interface works pretty well, but the key takeaway -- from a long-time SLI user -- is that if it's too difficult for one card, it's too difficult for two cards. In other words, SLI will help jump a playable framerate into "fluid" territory, but it won't help an unplayable framerate become playable. If one card can't consistently produce frames in under ~50ms (20fps), then the frame delivery won't be consistent, and the driver can only do so much averaging to smooth out the inconsistencies.

THAT SAID, if you ARE getting playable framerates, SLI can definitely help. I went from ~31FPS in ENBRL Skyrim to vsync'd 60 going from single-card to SLI. That's an atypically good result, but sometimes it really does work that well. (´・ω・`)
